Seiko SPB149
The SPB149 is Seiko's 2020 re-edition of the 1965 62MAS, their first modern dive watch. At 40.5mm with the 6R35 automatic movement (70-hour reserve), 200m water resistance and sapphire crystal, it delivers Swiss-adjacent specs at roughly one-third the price of the Tudor Black Bay 58.

The SPB149 is the microbrand shopper’s most cited reference for “what you’re giving up when going Swiss”. At €1000 street, it delivers 80% of the Black Bay 58 experience — the remaining 20% is in-house-COSC movement, finishing refinement, and resale value.
Frequently asked questions
- Is the SPB149 the same as the 62MAS?
- The SPB149 is a modern re-interpretation of the original 62MAS (reference 6217-8001) released in 1965. It preserves the case silhouette and dial layout but uses modern materials (stainless steel, sapphire crystal) and movement (6R35 vs the original 8L35 predecessor).
- Does the SPB149 have a sapphire crystal?
- Yes. Seiko equipped the SPB149 with a domed sapphire crystal — a notable upgrade over the Hardlex (mineral) crystals used on entry-level Seiko divers like the SKX series.
- What's the real-world accuracy of the 6R35 movement?
- The Seiko 6R35 is specified at -15/+25 seconds per day. In practice, most owners observe -5/+15 seconds per day after regulation, with individual variation based on orientation and wear patterns.
